"The clock is set using the buttons on the steering wheel. Use the 2 buttons that looks like 2 sheets of paper to scroll to "settings", then press either the up or down arrow. Scroll to "time/date" with the + and - button. Select time/date with the up or down arrow. Change time and date with the + and - button. Then you must press the black stalk sticking out of the instrument cluster (reset button) to confirm the change."
